WELDING WIRE COMPOSITION Russian patent published in 2010 - IPC B23K35/30 C22C38/58 

FIELD: chemistry.

SUBSTANCE: invention relates to metallurgy of complex alloyed welding materials and can be used in welding pearlite class steel components together and for welding to austensite class steel components. A welding wire composition is proposed, containing the following in wt %:carbon 0.08-0.12, silicon 0.15-0.35, manganese 1.0-2.0, chromium 15.0-17.0, nickel 24.0-27.0, molybdenum 5.5-7.0, nitrogen 0.10-0.20, aluminium 0.05-0.10, titanium 0.05-0.12, yttrium 0.05-0.10, iron and impurities - the rest. Total content of silicon, aluminium and titanium lies in the range: 0.28≤Si+Al+Ti≤0.55 wt %, content of sulphur and phosphorus impurities does not exceed: S≤0.010 wt %, P≤0.015 wt % and total content of sulphur and phosphorus does not exceed: S+P≤0.020.

EFFECT: increased strength of weld metal during flux welding or in an argon medium, which reduces welding labour input.
